opened or closed; this'being the result of the construction of the door itself, mammner in which the door is 'supported,'and also the special means provided for manipulating the door. It has-for afiirther object improved means for sealing the door in'its closed position and other objects 'willbeaiiparent from a consideration of the accompanying drawings and' description thereof. Of the accompanying drawingsFiglire' 1' is an elevation of the door andthesupporting means which embody features of invention. Figs. 2, 3, l and 5' are enlafged sections along the respective lines 2 2, 3 -3, l-4l, and 5'5 of Fig. 13 i 'The door itself may be constructed iii any suitable manner, so far as certain features of my invention are concerned; but as a part of my invention I prefer a door 10 composed of sheet steel having flanges 11, 12, 13 and 14, on its respective edges; these'flangesbeing partly to stiffen the door and bein also for purposes hereinafter specified. also prefer to make the door out of two pieces, 15 and 16, the upper piece l51bei1rg of somewhat thinner gage thanthe lower pieeeglso as" to decrease the expense, and also; the

In making the" do'or 'I provide otherflange's 17 andlS alongthe adjacent edges of the two portions ofthe door, and fasten these together in suitable manner, such as by means of r'ivetsor by w elding. I also provide otherstifiening means such as the corrugations 1 9 presse'dfin' the metal, these corrugated portionsexteiiding outwardly, as indicated in 'Fig. 21

At the same time I pre- I position of the flange'SQl and 25, with re'fsaucers-the rollers, is such that the weight ofth'e door tends to hold it in the closed in plaeGWh-efi opel'ied or closed, I provide the additional or projections '26, which," whenthe do s in the clo ed or open position,-'wedge gainst' the'innersurface of the roller supporting'brachets 27.

By this arrangement therew ill be no tendency for therollers to I run off I of the track, as the arrangement is such that this is substantially impossible. Also moisture and dirt cannot work down through the upper portions of the support because of the integral'arrangement of the supporting track; and the relative arrangeparent that a track support, such as shown,

and the Z-shaped stop may be cheaply made, and also that they will be very efficient and effective in fulfilling their functions.

In order to form suitable and effective sealing means, I provide in the flange 14 of the door, and in the central portion of the stop 38, registering openings through which sealing means may be inserted; and to remove the strain entirely from the seal I provide the U-shaped sealing memberBG, having eyes 37 at the ends of its arms; and by passing one of the arms of this member through the registering openings, when the door is closed, an ordinary seal 38 may be sealed across the two arms, as indicated, and the door will be locked firmly closed, ina very simple and effective manner.

I claim as my invention:

1,. A door having supporting rollers on the upper edge thereof, rollers positioned beneathsaid door, a track fixed un er the upper rollers which supports said upper rollers when the door is partly opened, means fixed to said door which pass upon said lower rollers when the door is entirely closed or open, and a flange projecting upwardly from said upper track outside of said upper rollers.

2, The combination of a door frame .and a door, means for supporting said door when the door is partly opened, two rollers adjacent the lower rear corner of said frame, and means projecting downward from the lower rear corner of said door, said latter means resting on said two rollers when said door is closed thereby supporting the rear edge of said door.

'3. A door having supporting rollers on Y the upper edge thereof, rollers positioned beneath said door when it is either open or closed, a track fixed under the upper rollers 'which supports said upper rollers when the dooris partly open, and flanges depending from the lower edge of said door which run upon said lower rollers and raise the door from said upper rollers as the door is entirely closed.

4:. A door having supporting rollers on the upper edge thereof,.rollers positioned beneath said door when it is either open or fully closed, a track fixed under the upper rollers which supports said upper rollers I when the door is partly open, and flanges depending from the lower edge of said door which run upon said lower rollers and raise the door from said upper rollers as the door entirely closed,said depending flanges being spaced apart slightly unlike the said lower rollers.

5. A sliding door, means adjacent the upper edge of said door for supporting said door when said door is partly open, and

rollers beneath said door for supporting it when it is in its closed or open position;

6. The combination of a door frame and a door, means for supporting said door by its upper edge when the door is partly open, two adjacent rollers adjacent the lowerrear corner of said frame, and a flange projecting downward from the lower rear corner of said door, said flange resting'on said two rollers when said door is closed and thereby supporting the rear edge of said door.

7. The combination of a door frame and a door, means for supporting said door by its upper edge when the door is partly open, two adjacent rollers adjacent the lower rear corner of said frame,and a flange projectdownward from the lower rear corner of said door, said-flange resting on said two rollers when saiddoor isclosed and'thereby supporting the rear edge of said door, the lower edge of said flange being convex.

The combination of a door frame and a door, means for supporting said door by its upper edge when the door is partly open, two adjacent rollers adjacent the lower rear corner of said frame, and a flange projecting downward from the lower rear corner of said door, said flange resting on said two 9. -A sliding door,'means adjacent the up- 7 per edge of said door for supporting said door when sald door ispartly open, and

means beneath said door, for supporting it when it is in its closed or. open position, and means for binding said door snugly in place when it is in its closed'position. v

10. A door having supporting rollers on the upper edge thereof, rollers positioned beneath said door, a track fixed under the upper rollers which supports said upper rollers when the door is partly opened, means fixed to said door which pass upon said lower rollers when the door is entirely the lower rear corner of said frame, and closed or open, and a flange projecting upmeans projecting downward from-the lower 10 wardly from said upper track outside of said rear corner of said door, said latter means upper rollers and extending to and secured resting on the forward side of said roller '5 to the wall. when said door is closed. 7
